  Log:
  Add a missing com_unlock() to the serial port drain test code.  This code
  is necessary to detect non-existant serial ports on machines (such as the
  eMachines laptop) which don't have any serial port hardware at all, but
  the missing com_unlock() caused systems to crash in certain situations for
  obvious reasons.
  
  Many thanks to Glenn Johnson <glennpj@xxxxxxxxxxx> for keeping on my back
  about the issue and for testing the fix.  This should also fix the last of the
  serial-port related bug reports stemming from the original 1.0A release.
